PSK AND QAM Modulation
Dear Sir/Ma,
I am trying to design a PSK and QAM modulation for underwater optical system. The PSK Modulator and QAM Modulators on Optisystem are electrical PSK Modulator and QAM PSK Modulators and I want to connect it to a CW Laser so I designed the simulation attached. I would like to know if these setups are correct. I noticed that when I increased the distance on the matlab code from 10cm to 100cm the Q-factor increased and it ought to decrease. What could be the problem on my setups? I look forward to hearing from you thank you.
